HYDROCARBON=BURNER.

SPECIFICATION forming part of Letters Patent No. 659,668, dated October16, 1900.

Application filed July 3, 1900. Serial No. 22.443. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT E. HARTEL, a resident of Philadelphia, in thecounty of Philadelphia and State of Pennsylvania, have invented certainnew and useful Improvements in Hydrocarbon -Burners; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in hydrocarbon-burners, oneobject of the invent-ion being to provide a device of the abovementionedcharacter which will preclude any possibility of unvaporized hydrocarbonpassing to the burner.

A further object is to provide an improved hydrocarbon-burner which willprevent the transmission of heat to the hydrocarbonsupply.

A further object is to provide improved means for starting vaporizationin the retort or vaporizer.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in section illustratingmy improvements, and Fig. 2 is a viewin elevation taken at right anglesto Fig. 1.

A represents a casting provided internally with a partition 1, formingtwo compartmentsnamely, the vaporizing chamber or retort 2 and a chamber3, to which the Vapor is supplied. The vaporizing chamber or retort 2 isapproximately U-shape in side View and is provided at its inlet end withanine. 4o ternally-screw-threaded collar 4, into which is screwed theend of an air-supply pipe 5, inclosing or surrounding thehydrocarbonsupply pipe 6. The other end of the vaporizing-chamber ismade with a threaded hole, into which is screwed the threaded contractedend of an inverted conical dome 7, which latter is provided on its topwith an angular enlargement 8 for the reception of a wrench tofacilitate screwing the same into proper position.

Apipe 9 is screwed into an opening in the partition 1, so as tocommunicate with the chamber 3, and extends up through the con tractedlower end of dome '7 and terminates near The top thereof.

A pipe 10 is screwed into the lower end of chamber 3 and is curved atits lower end and internally screw threaded, into which is screwed anipple 11 on the lower end of a coinmingling-chamber 12, said nipplehaving a contracted opening therein to permit but the proper flow ofvapor into the comminglingchamber, and an asbestos disk 13 is held inposition at the bottom of the comminglingchamber by the latter beingscrewed down onto the pipe 10, and perforations 14 are made in thebottom of the commingling-chamher to permit the passage of oiltherethrough to the disk to saturate the latter for preliminary heatingof the vaporizing-chamber, as will be more fully hereinafter explained.

Air-inlet openings 15 are provided in the side walls of thecommingling-chamber near its lower end, for the admission of air to bemixed with the vapor and be burned at the burner 16, screwed onto theupper end of the commingling-chamber to direct the flame against thevaporizing chamber or retort.

The pipe 10 is provided in its rear and side walls with openings 17,adapted to communi- 8o cate with vapor-pipes 18 for supplying vapor toadditional burners 19, one of which latter is shown in Fig. 2.

The operation of myimprovements is as follows: To start the burner, oilis poured through the openings 15 in the comminglingchamber 12 and willpass through perforations let and saturate the asbestos disk 13, whichlatter is ignited, and the flame will pass up through the perforations14 and burner 16 and around the outside of the commingling-chamber 12 toheat the vaporizing chamber or retort 2, into which hydrocarbon issupplied by pipe 6 and air under pressure by pipe 5, and the heat of theburning oil on 5 the disk 13 will vaporize the hydrocarbon in the retort2 and the same will pass up into dome 7 and down through pipe 9, chamber3, pipe 10,and into the comniingling-chamber 12, where it will bethoroughly mixed with air :00 entering through openings 15 and the mixedair and Vapor fed to the burner 16, which will be ignited by the flamefrom the burning-disk 13 and the operation of vaporization maintained bythe burner 16 after the flame from the disk has been extinguished. Thevapor will also be supplied to the pipes 18 and burners 19, asheretofore explained.

It will be seen that by employing the dome 7 any possibility ofhydrocarbon unvaporized passing through pipe 9 is prevented, as thecontracted lower end of the dome serves as a shield to stop the passageof hydrocarbon into the dome, and even though a verysmall quantityshould escape through the contracted end of the dome the invertedconical shape of the interior of the latter will direct the same backinto the retort and absolutely prevent its entrance into pipe 9, and itwill also be seen that by inclosing the hydrocarbon-inlet pipe 6 in theair-supply pipe 5 the former is always surrounded by a current of airand the heat of the retort cannot be communicated thereto. Hence thedanger of overheating the hydrocarbon-supply is entirely obviated.

Various slight changes might be resorted to in the general form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I would have it understoodthat I do not wish to limit myself to the precise details set forth, butconsider myself at liberty to make such slight changes and alterationsas fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I ,claim as new, and desire Tosecure by Letters Patent, is-- l. A hydrocarbon-burner comprising aretort, a dome supported upon and communicating therewith by acontracted opening, a vapor-pipe communicating with the upper portion ofthe dome, a burner under the retort and means for conducting vapor fromsaid vapor-pipe to the burner.

2. A hydrocarbon-burner comprising a retort, a dome in communicationtherewith, a vapor-pipe communicating with the upper portion of saiddome, and a burner arranged to discharge against said retort, said domebeing situated in the path of the products of combustion from theburner.

3. A hydrocarbon-burner comprising a retort, a dome in communicationtherewith, a vapor-pipe-communicating with the upper portion of saiddome, and a burner arranged to discharge in the direction of the retortand the dome, said retort being situated between the burner and thedome.

4. A hydrocarbon-burner, comprising a retort, a dome located over andcommunicating therewith by a contracted opening and a vapor-pipecommunicating with the upper portion of the dome and passing throughsaid contracted opening and the retort.

5. In a hydrocarbon-burner, the combination with a retort, of ahydrocarbon-supply pipe communicating with said retort and inelosed inan air-supply pipe, an inverted conical dome communicating with theretort, a vapor-pipe communicating with the upper portion of the domeand passing through the retort and adapted to supply vapor toa burnerfor heating the retort.

6. A hydrocarbon burner, comprising a casting, a partition thereinforming a vaporizing-chamber and an outlet-chamber for vapor, a domecommunicating with the vaporizing-chamber and a pipe passing through thevaporizing-chamber and connecting the vapor-outlet chamber with theupper portion of the dome.

7. In a hydrocarbon-burner, the combination with a retort and a pipecommunicating therewith,ofa commingling-chamber screwed into said pipe,a disk of incombustible fibrous material held between the com mingling-chamber and pipe, and the commingling chamber provided withperforations through which oil is poured to saturate the disk, whichlatter, when ignited, is adapted to heat the retort and startvaporization therein.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
